Feature Request: Docker-Compose autocompletion

[mityax]

What problem will this feature address?

Autocompletion (e.g. based on a json schema for docker-compose.yml) would be really helpful as one could immediately see which options one has when writing a raw compose file. This would make the UI even fancier :)

Describe the solution you'd like

Just a very simplistic auto completion would be enough; only the supported yaml fields would already be amazing.

Also, I'd guess depending on how this is implemented, a syntactic validation (e.g. json schema) wouldn't be much additional effort then anymore and would surely also be a nice to have.

Describe alternatives you've considered

I wouldn't know about alternatives to this.

Additional context

No response

Will you send a PR to implement it?

No

This sounds like a good idea, I think we internally handle the json schema of the compose spec.
